A 120 volt circuit shall be added for the climate control while the gantry crane is in the resting position. All panels with hinged door panels shall be keyed. (3) Gantry and travel motions shall be controlled by open-loop vector VFDs. All VFDs shall be provided with drive isolation transformers. All VFDs shall use dynamic braking to control motion, and dynamic braking resistors shall have thermal capacity of Class 160 series or better, rated continuous duty. (4) All motors shall be TEFC or TENV as necessary to maintain temperature ratings. The motors will be inverter-duty with Class F or H insulation to maintain appropriate temperature rise. (5) The gantry drive master switch shall have a drift button for coasting. (6) The hoist drive shall be single speed relay controlled.
